Around 2,000 civilians are on evacuation buses heading from the coastal city of Berdyansk to the Ukrainian government-held city of Zaporizhzhia, carrying civilians evacuating from the besieged city of Mariupol.
"The evacuation convoy left Berdyansk for Zaporizhzhia," Mariupol city council said in a statement on Telegram. "Many private vehicles have joined the 42 buses escorted by Red Cross and SES (State Emergency Service) vehicles. Today we expect the arrival of a record number of Mariupol residents."
Some background: Russia's ministry of defense said in a statement on Thursday that the Russian military would reopen the evacuation corridor from the besieged city of Mariupol to Zaporizhzhia on Friday at the request of French and German leaders.
The ministry's announcement came as Ukrainian officials said that humanitarian convoys ran into several issues on Thursday, including Russian troops confiscating aid and blocking buses.
Russian forces had confiscated 14 tons of humanitarian aid from buses bound for Melitopol in southern Ukraine, according to Ukranian minister Iryna Vereshchuk.
Vereshchuk said the food and medication was loaded on 12 buses. She added that Russian forces also blocked 45 buses going to Berdyansk on Thursday en route to Mariupol, where about 100,000 civilians remained trapped.
